AmberSep GT75 Chelating Resin is alkyl thiol-functionalized, which provides very pronounced selectivity for certain metal ions such as mercury, rhodium, copper, silver, cadmium, and lead.
AmberSep GT75 is a uniform particle size resin that has been developed for the rapid removal of mercury from different solutions and gaseous streams. Although it has a lower capacity than AmberSep GT74, it can be regenerated more readily and efficiently with hydrochloric acid.
The special properties of AmberSep GT75 make it useful for problems where removal of metal ions in addition to Hg—such as Cu, Ag, Pb, and Cd—is also desired. Applications may be found in different fields of chemical technology, for example: wastewater treatment, flue gas desulfurization blowdown, recovery of solutions and metals in the plating industry, recovery of catalysts, and removal of interfering ions in hydrometallurgy.
